On pressure-enthalpy diagram for R-134a, mark the lines that represent the following processes:

Isentropic compression from statured vapor at 20 F to a pressureat 150 psia;

Adiabatic throttling of saturated liquid at 100 psia to aquality of 40%;

Isothermal line of 100 F for heating of saturated liquid to asuper-heated vapor at pressure of 10 psia;

Isobaric cooling (and condensation) of a super-heated vapor at100 psia and 220 F to a saturated liquid; what’s the correspondingratio of sensible heat to latent heat of this process?
